Abstract
Our understanding of critical climate tipping points and their impact on future Arctic and global climate remains limited due to the shortness of our observational records and our inability to quantify past changes in sea surface temperatures and the carbonate system in Arctic or Subarctic Oceans. Project SiTrAc addresses this critical gap by pioneering a new holistic multidisciplinary approach to palaeoceanographic proxy development that considers foraminifera as a living organism and not just as a proxy carrier. Using innovative biogeochemical techniques and micro-structural analyses of polar foraminifera Neogloboquadrina pachyderma (NP), which is the dominant and often only species present in surface waters below 4C, SiTrAc will track essential climate variables via the living proxy into the archive (i.e., marine sediments). The main objective for survey CE23011 was to quantify biological and physiochemical processes, that influence how geochemical tracers of climate are recorded in NP.
